SOLUTION

If a coordinate is refleted over the x-axis, the formula to apply is

[tex](x,y)\rightarrow(x,-y)[/tex]

So for B(-5, -5), this becomes

[tex]\begin{gathered} B\mleft(-5,-5\mright)\rightarrow(-5,-(-5) \\ \\ the\text{ answer becomes } \\ \\ B(-5,-5)\rightarrow B^{\prime}(-5,5) \end{gathered}[/tex]
